So - got me some new sealed non-AD struts from Univair. They came primed. Univair sales dude told me on the phone that they use cheap primer and most folks remove it and apply 2-part epoxy primer before shooting color.

No problem - thought I'd blast them with walnut shells. Wow - this would take a week. Stepped up to aluminum phosphate - not much better. Now realizing we have a better life through chemistry - stepped up to chemical stripper. After 3 hours of caustic chemicals and scrubbing with scotchbrite - the primer is still not fully removed...

Soooo... Do you kids just use the primer Univair ships with? or do you strip it?

With what? Now I'm thinking of punting and taking them to a professional industrial media blaster and have them take it down to bare metal so I can epoxy it. Seems soda blasting with 6 digits worth of equipment is the next step. I don't want to mess up $2500 worth of struts.

Did I screw up? Am I on the right track?
